Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LA ELABORACION DE PIEZAS EN BRUTO DE NUCLEOS PARA FUNDICION, DONDE (A) SE ELABORA UNA MEZCLA BASANDOSE EN ARENA DE MOLDEO RESISTENTE AL FUEGO, INORGANICA Y UN AGLOMERANTE INORGANICO SOBRE LA BASE DE VIDRIO ACUOSO, (B) LA MEZCLA SE VIERTE EN UNA CAJA DE NUCLEO ATEMPERADA, (C) SE EXTRAE EL AGUA CONTENIDA EN LA MEZCLA MEDIANTE UNA VIA FISICA Y (D) LA PIEZA MOLDEADA EN BRUTO DE NUCLEO SE SACA DE LA CAJA DE NUCLEO. EL PROCEDIMIENTO SE CARACTERIZA DE TAL MODO QUE (E) LA CAJA DE NUCLEO ATEMPERADA ES SOMETIDA A DEPRESION DURANTE EL LLENADO, (F) EL TIEMPO DE PERMANENCIA/ TEMPERATURA SE AJUSTA DESPUES DEL CIERRE DE LA CAJA DE NUCLEO DE TAL MODO, QUE SE FORMA UNA CUBIERTA DE BORDE DIMENSIONALMENTE ESTABLE Y CON BUENA CAPACIDAD DE SOPORTE SOBRE EL BORDE DE LA PIEZA MOLDEADA EN BRUTO, (G) LA PIEZA MOLDEADA EN BRUTO DE NUCLEO SE RETIRA INMEDIATAMENTE DESPUES DE LA ABERTURA DE LA CAJA DE NUCLEO Y, BAJO EL EFECTO DE MICROONDAS, ES SOMETIDA A UN SECADO COMPLETO.THE INVENTION CONCERNS A PROCEDURE FOR THE PREPARATION OF PIECES IN GROSS OF NUCLEOS FOR FOUNDRY, WHERE (A) A MIXTURE IS PREPARED BASED ON MOLDING SAND RESISTANT TO FIRE, INORGANIC AND AN INORGANIC BINDING BASE ON GLASS BASE (GLASS BASE) ) THE MIXTURE IS Poured into a TEMPERED NUCLEUS BOX, (C) THE WATER CONTAINED IN THE MIXTURE THROUGH A PHYSICAL ROUTE AND (D) THE MOLDED PIECE IN GROSS OF NUCLEO IS REMOVED FROM THE NUCLEUS BOX. THE PROCEDURE IS CHARACTERIZED IN SUCH A WAY THAT (E) THE TEMPERATURE NUCLEUS BOX IS SUBJECTED TO DEPRESSION DURING FILLING, (F) THE PERMANENCE / TEMPERATURE TIME IS ADJUSTED AFTER THE CLOSURE OF THE NUCLEUS BOX OF SUCH MODE, WHICH IS FORMED A DIMENSIONALLY STABLE EDGE COVER AND WITH GOOD SUPPORT CAPACITY ON THE EDGE OF THE GROSSED MOLDED PART, (G) THE MOLDED MOLDED PIECE IS REMOVED IMMEDIATELY AFTER THE OPENING OF THE NUCLEUS BOX, MICROWAVE, IS SUBMITTED TO A COMPLETE DRYING.
